The Food and Drug Administration released draft guidelines Wednesday aimed at regulating lead levels in lipstick and other cosmetic products.

The agency recommended a maximum lead level of 10 parts per million (ppm) in certain cosmetics, including lipstick, lip gloss, eye shadow, blush and body lotion. The guidance does not apply to “topically applied products” that are drugs or hair dyes, the agency said.

“We consider the recommended maximum lead level to be achievable with the use of good manufacturing practices and to be consistent with the 10 ppm maximum lead level for similar products recommended by other countries,” the FDA wrote.

The agency noted that lead can appear as an impurity in cosmetic ingredients due to its “background presence” in the manufacturing environment.

“In our surveys, which do not necessarily reflect the full range of products that are currently on the market, a small number of samples had lead levels that exceed the maximum level we are recommending,” the agency said. “Our goal is to ensure that cosmetic lip products and externally applied cosmetics do not contain lead as an impurity at levels that would pose a health risk.”

Even if you consider yourself to be pretty upbeat, it’s easy to get caught up in feelings of dread as you wait to hear about uncertain news. As the moment of truth draws nearer, people often find themselves increasingly convinced that bad results are ahead.

These emotions may feel stressful and unhealthy, but a new study suggests they’re totally normal. In fact, this instinct to brace for the worst can actually be protective and serve as a buffer against potentially bad news, say researchers from the University of California Riverside.

In previous studies, it’s been recognized that, as individuals wait for their respective results, students become increasingly convinced they’ve failed an exam, patients become increasingly convinced they have a terrible disease, and voters become increasingly convinced that their candidate will lose an election.

Kate Sweeny, Ph.D., a psychology professor at UC Riverside, wanted to see if this was true of optimists and pessimists alike. “Intuition might suggest that some people are more likely to brace than others,” Sweeny said in a press release. “In particular, happy-go-lucky optimists would seem immune to the anxiety and second-guessing that typically arise as the decisive moment draws near.”

So she and her co-author performed nine different experiments in their lab and in real-life settings. Some involved college students anticipating rankings of their attractiveness from peers, for example, while others involved law-school graduates awaiting the results of their bar exams. All participants answered questions beforehand to determine their natural disposition.

The researchers’ findings, published in the Journal of Personality, were “counter to intuition,” Sweeny said. “Optimists were not immune to feeling a rise in pessimism at the moment of truth. In fact, not a single study showed a difference between optimists and pessimists in their tendency to brace for the worst.”

There was a difference, unsurprisingly, in overall predictions: Optimists started out with more positive expectations than pessimists. But everyone in the study tended to shift those expectations downward over time.

This may be because not getting one’s hopes up can be a natural defense. “If you expect the worst, you can lessen feelings of shock and disappointment if things don’t go as you hoped,” Sweeny told RealSimple.com, “and you’ll be pleasantly surprised if they do.”

So if you feel down right before a big announcement, Sweeny says you shouldn’t necessarily fight those feelings. Rather, she says, we should all try to be more like the optimists in this study, and save our pessimism for these strategic moments.

“It’s generally good to be optimistic about the future,” she says…

One thing that people don't do often enough is just stand and extend their arms out—really reaching through the chest while relaxing the shoulders. The simple act of holding your arms outstretched, either to the side or in front, is quite fatiguing. Why? It's a new movement that the body must build the strength to sustain. And that's what you want. Add weights and you'll sculpt the entire arm, as well as further strengthen it, building even more muscle. And we all know that the more muscle you have, the more calories you can torch at rest. Another reason to tighten up: As we age, the skin starts to sag, but toning helps you fight back. OK, time to get defined!

Go through this sequence twice. And don't forget your 30 to 60 minutes of cardio six days a week.
